What is the most common reason for changing the PAP interface during titration?

The most common reason for changing the PAP (Positive Airway Pressure) interface during titration is linked to unacceptable leak values. During a titration study, maintaining an effective seal is crucial for the therapeutic benefits of PAP therapy, as a significant leak can undermine the pressure delivered, making it less effective in preventing airway collapse during sleep. An unacceptable leak can lead to insufficient therapeutic pressure, causing the treatment to fail in alleviating sleep apnea symptoms, which is why practitioners prioritize addressing this issue promptly.

Monitoring leak levels is an integral part of the titration process; when leaks exceed acceptable levels, it necessitates an adjustment in the interface to ensure that the patient receives the correct therapeutic intervention. While factors such as patient comfort, compliance, and machine noise are also important, a high leak rate is the most immediate and direct threat to the efficacy of the treatment being provided during a titration study.
